Operating DC Circuit Breakers With MMC [PDF]
IEEE Transactions on Power Delivery, 2018 High Voltage Direct Current (HVDC) grids may be protected from dc faults through the application of HVDC circuit breakers. Recent advances in dc circuit breaker technologies may allow faults in the dc grid to be cleared without a permanent loss of power to the connected ac grids.
